Hi,
I am reporting problem in unsteady flow over circular cylinder tried using simple and pisoFoam. I used the converged solution of simpleFoam into pisoFoam. solution appears stable with a Co around 0.2. the forces and the coefficients come out very small. lift coefficient comes out many orders small. I have checked for possible errors in controlDict (Aref, lref etc.). the coefficients remain constant after some time. I went back to view the simulation of the fields and found no change happening after a few time steps. I am attaching my case here with only 0, forces, forceCoeffs directories. Could someone find out the error ? regards, achyutan |

Hi,
sorry that i didnt attach system directory for viewers to check controlDict. I have attached now. I would really appreciate replies here as nothing comes to my mind on this. waiting for response.. achyutan |
